The problem of Hardware Trojans detection in System-on-Chip

This paper describes a new threat to the security of integrated circuits (ICs) called Hardware Trojans. Such alterations can be embedded in safety critical, security and military systems, such as weapon control systems, battlefield communication systems, information collection and decision making systems, satellite electronics, banking systems, cryptosystems, etc. The reason is the current trend of IC fabrication migration to low-cost foundries, where additional malicious circuits can be inserted by adversary that could result in functional changes and the whole system failure. The goal of the paper is to describe security problem in IC manufacturing, analyze the existed methods with their bottlenecks for effective Trojan detection in large ICs, such as system-on-chips (SoCs).
